Dokgett

Introduction

Dokgett is a graphical autoring tool developped at the ASTUS lab (U. of Sherbrooke), written entirely in Java. I here describe the latest version that I have worked on during my M.Sc. and Ph.D.

Dokgett allows to visually design cognitive models. Its interface shown below comprises two main parts. The left part allow to add knowledge components (concepts, procedures and goals) and to connect them together visually. The right part allows to edit the properties of the selected knowledge component.



The software has several menus offering advanced options. Here is a screen capture of the menus.



The files that are generated by Dokgett are named DOK/SPK. They are read by an interpreter that I have developped to "execute" cognitive models [1, 3]. To get more information about this interpreter and the theoritical foundations of the cognitive model click here.
